The ROHS3 compliance covers current environmental regulations across EU and most global markets. No pin-compatible alternative is listed in the evidence; if dual-sourcing is required, verify the second source's AEC-Q100 qualification and pin-to-pin compatibility through your own qualification process.","metaTitle":"STMicroelectronics L9945TR Automotive Smart Power IC","metaDescription":"STMicroelectronics L9945TR PTS smart power IC, AEC-Q100 qualified for automotive.

This qualifies it for use in under-hood and cabin electronic control units, subject to the OEM's own qualification requirements."},{"question":"Is L9945TR a direct replacement for L9945?","answer":"Yes, the L9945TR is functionally identical to the L9945 — the 'TR' suffix indicates tape-and-reel packaging only. It is a drop-in replacement for the same base part number when ordered in tape-and-reel format for automated assembly."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/L9945TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/L9945TR when reusing this data.
